Process Flame cutting
A traditional method for cutting metals, especially thick plates e.g. for shipbuilding. Most geometries can be made. The major drawback is the heat introduced into the material and the following thermal distorsions.

A high temperature flame (about 3000 c) made from a mixture of fuel gas (e.g. acetylene) and pure oxygen heat the material in the cutting region resulting in a combination of rapid oxydation and melting. The oxides / the melt is blown away by the gas pressure.
Danish Name Flammeskæring
Category Reducing processes, Cutting
Materials Metals
Typical products Shipplate
Competing processes Plasma cutting
Angle grinder
Price notes Fairly low cost equipment.

Variable cost comes from consumed gas and oxygen and correction work needed after thermal distorsions.
Environmen- tal notes Use: Working environment problems from undesired gasses and intense light require that ventilation and protection glasses must be used.
Keywords Sheet metal cutting
